Information

Big Southern Butte is one of three rhyolitic domes near the center of the Eastern Snake River Plain. The area supports vegetation such as lodgepole pine, aspen, Douglas fir, and manzanita (not common to this region). This impressive formation is one of the largest volcanic domes in the world, yet is one of the youngest (300,000 years old). Hikers who trek to the top of this 7,550-foot high summit are rewarded with spectacular panoramic views stretching for miles.
